NEMIX RAM 16GB DDR5 4800 ECC RDIMM

This NEMIX RAM module provides 16GB of DDR5 ECC registered memory for compatible HPE servers and workstations. It operates at 4800MHz with a CAS latency of CL40 and a voltage of 1.10V. The single-rank 1Rx8 design uses major OEM chips from Samsung, Micron or Hynix. The 288-pin RDIMM form factor fits registered DIMM slots in qualified HPE systems.

Suited for HPE servers needing registered ECC memory

This module suits administrators upgrading HPE servers such as those using part numbers P58354-H21 or P62601-B21 where registered ECC RDIMMs are required. It is not suitable for platforms that accept only unbuffered UDIMM memory or for desktop PCs lacking registered DIMM support. Buyers needing non-ECC memory or higher capacity per module should look at other configurations.

Registered ECC RDIMM with CL40 latency

The defining specification is the registered ECC RDIMM architecture combined with CL40 latency at DDR5 4800 speed. This combination determines compatibility with HPE server memory controllers that require registered buffering and error correction. Verify the system qualified vendor list for the exact part number MR38400-618K1 before ordering.

Questions about this item

How do I install this 288-pin DDR5 RDIMM in my HPE server and what is the common mistake?

Power down the server, open the chassis, align the notch on the 288-pin module with the slot key, press firmly until the ejector clips lock, then verify the system recognises the 16 GB at 4800 MT/s. The step often missed is seating the module fully so both clips engage; a partial insert causes boot errors.

What maintenance or replacement will this ECC RDIMM need over its service life?

The module has no heat spreader and no moving parts, so no routine maintenance is required. If a correctable error count rises above the platform threshold, the DIMM should be replaced; otherwise it runs for the server's lifetime.

What limit appears first when this 1Rx8 CL40 1.1 V module runs sustained workloads?

The primary limit is the CL40 latency at 4800 MT/s; sustained bandwidth is capped by the single-rank 1Rx8 organisation and the 1.1 V JEDEC voltage, so throughput plateaus before thermal throttling becomes a factor.
